Hi there,
I was working in a lab before I became an entrepreneur. I started it as a hobby but the revenue was so good that I hooked on to it. I started my own online business of selling handmade soaps. I started getting orders from across the country and my business has expanded. I have now decided to start a B2B ecommerce business where I will be selling my soaps and perfumes to various businesses which can use them, such as hotels, Air BnB and other accommodations. It becomes so much easier to operate when you know the different models. Here is an article that explains them.
